Vedclass · Answer

(A) In amplitude modulation,the amplitude of the carrier wave is varied in accordance with the instantaneous value of the modulating signal.Mathematically,the modulated wave consists of the carrier frequency $(f_c)$ and two sideband frequencies: the upper sideband $(f_c + f_m)$ and the lower sideband $(f_c - f_m)$,where $f_m$ is the frequency of the modulating signal.Therefore,amplitude modulation consists of one carrier frequency and two sideband frequencies.
